If you’re a guy, you can thank the testosterone you have -- and the extra estrogen you don’t -- for your weight-loss edge. On average, women have between six and 11 percent more body fat than men, an assumed evolutionary adaptation to help during pregnancy. From puberty to menopause, women maintain more average body fat than men -- even when they take in fewer calories.
The most controversial part of this diet is the severe fat restriction. The American Heart Association recommends a diet with 25% to 35% of your calories from fat. The Pritikin Principle requires you consume less than 10% of your calories from fat. Besides providing taste to your diet, dietary fat has other functions, and 10% may be too low to meet your needs. There has been a considerable amount of research showing the health benefits of omega-3 fats, including protecting your heart. The American Heart Association now recommends that people without coronary heart disease eat a variety of omega-3 fat-containing fish at least twice a week and that those with coronary heart disease consume one gram of omega-3 fats per day. Dietary fat is also needed to transport the fat-soluble vitamins A, D, E, and K. Without fat to transport them, they will not be able to serve their functions in your body.
The primary advantage to this diet is that you will lose weight if you eat what you are given. Portion-and-calorie-controlled meals are great tools for long-term weight loss and maintenance. They take away the guesswork of how many calories you consume, they can be nutritionally balanced, they are quick and easy to prepare, and they teach you about healthy portion sizes.
4. Core exercises – pick up a decently weighted kettlebell (maybe 25-30 lbs depending on your size and strength) and spend even 15 minutes a day doing a quick routine with them. Something like a kettlebell swing, pushups, and mason twists (this is a very common workout for me now). I do 4-6 sets of 25/15/20 of the above. It’s a great little workout and really doesn’t take any longer than 15-20 minutes.
“A study published in Nutrition Journal found that participants who ate foods high in monounsaturated fats for lunch (in this case, half an avocado) reported a 40 percent decreased desire to eat for hours afterward. Monounsaturated fats from sources like olive oil, nuts and avocados can reduce cholesterol, promote weight loss, even boost memory.” — David Zinczenko, author of the Zero Belly Cookbook
“If you are looking to speed up weight loss, adding 30 minutes of cardio three times per week will certainly help burn calories and body fat,” says Amie Hoff, Certified Fitness Professional in New York City. Short on time? Hoff suggests a HIIT (High Intensity Interval Training) workout. “The idea is to push your body hard for a short burst with a period of recovery. I like to have people start with a 10 to 15 second sprint (run, bike, jump rope, run stairs or anything that gets your heart rate up) and then back off for 30 seconds to recover. As you get stronger, you will increase the sprint time and decrease the recovery period. A 15 minute HIIT session can be equivalent to a regular 30 minute cardio workout.”
The dietary focus on this diet also has some limitations. The idea of "good carbs" and "bad carbs" is controversial. While there is some truth to the role of glycemic index in hunger, it is not a guaranteed tool for weight management. Labeling foods as "good" and "bad" creates problems for people trying to develop healthy eating habits. A well-balanced diet requires whole wheat sources of starch, while allowing for some sugar.
The key to losing weight is to burn more calories than you eat and drink. A diet can help you to do this through portion control. There are many different types of diets. Some, like the Mediterranean diet, describe a traditional way of eating from a specific region. Others, like the DASH eating plan or a diet to lower cholesterol, were designed for people who have certain health problems. But they may also help you to lose weight. There are also fad or crash diets that severely restrict calories or the types of food you are allowed to eat. They may sound promising, but they rarely lead to permanent weight loss. They also may not provide all of the nutrients your body needs.
“Your body begins to work differently. This study proves that small amounts of nourishment throughout the day are better than the same amount of food concentrated in three big sittings. If we feed the body at regular intervals we send a signal to the body that it doesn’t have to store calories. Conversely, when we skip meals we send just the opposite signal for the body to store calories, creating a negative effect on the metabolism.” — Dr. Wayne Scott Andersen, co-founder and Medical Director at Take Shape For Life
One afternoon, a few years later, Christopher came home and announced that he wanted to try a macrobiotic diet. He’d read interviews with people who claimed that this diet made them feel balanced and happy and he was intrigued. I’d heard (incorrectly, as it turns out) that macrobiotics was only for sick people and that fish was a requisite part of the diet. No way was that for me! He looked at me with that sweet face of his and said, “Alright, baby. I’m going to do macrobiotics, but you don’t have to.”
The Core Plan is based on the science of energy density. Energy density refers to the amount of calories in a given weight of food. Foods that are considered low energy dense foods have a small amount of calories for a large volume of food (for example, vegetable soups, vegetables, and fruit). High energy dense foods provide a lot of calories for a small amount of food (for example, oils, butter, cream sauce). The Core Plan provides a "balanced diet by centering on a list of healthy foods that keep you full longer."
If all you have is two weeks to lose weight, you’re going to have to be very strict with this rule. Luckily you can still drink any water-based drink such as coffee and tea, so it’s not all bad. I usually have a huge glass of ice cold water plus one or two large cups of coffee in the morning to kick start my day. I often use cinnamon to flavour my coffee – it’s a great tip for those of you that really enjoyed adding milk.
Weight gain has been associated with excessive consumption of fats, (added) sugars, refined carbohydrates in general, and alcohol consumption. Depression, stress or boredom may also contribute to weight increase, and in these cases, individuals are advised to seek medical help. A 2010 study found that dieters who got a full night's sleep lost more than twice as much fat as sleep-deprived dieters.
"When going out for fast food, I used to get the large-size value meal. Now, I satisfy a craving by ordering just one item: a small order of fries or a six-piece box of chicken nuggets. So far, I've shaved off 16 pounds in seven weeks, and I'm on track to being thinner than my high school self for my 10-year reunion later this year." —Miranda Jarrell, Birmingham, AL
